Question

The RMS velocity of a gas at 0 degrees is 2 metre per second The RMS velocity of the same gas at 819°

Answer 1

Answer:

hey bud the answer is 4m/s I think it helps you

Answer 2

Answer:

4 m/sec

Explanation:

The given data is:

Temperature, T1=0+273=273 K

RMS velocity of a gas  at 0°C, C1=2 m/s

Temperature, T2=819+273=1092 K  

Then the RMS velocity of gas at 819°C ,C2=?

From the RMS velocity equation,

    C =  √3RT/m

For same gas at two different temperatures, their RMS velocities are as follows:

  C1/C2=√T1/T2

  Then,  2/c2 = √ 273/1092

     ⇒  2/c2 = 0.5  

∴C2 at  819 °C=4 m/s
